Exception in thread "main" java.lang.NullPointerException
        at test_grp.main(test_grp.java:70)

The error code displayed at the top of the stack is 0 in my
internal tests on Linux however the customer running the same
code from Windows receives a -79716 SQLCode.  The same code runs
successfully with Informix JDBC 4.10.JC12 and 4.10.JC13.  It
fails with Informix JDBC 4.50.JC3 and 4.50.JC4W1.

It does not matter if I pass the SSL_TRUSTSTORE and
SSL_TRUSTSTORE_PASSWORD at the command line or in the connection
string url.

Problem is easy to reproduce.  I have a single Connection
Manager in a group in my sqlhosts file like this:

# --- Group for CM ---
g_ss     group    -            -    e=ss_avail
ss_avail onsocssl njdc-lxphx01 9405 g=g_ss

I am using a SERVERSET in my Connection Manager configuration
file like this:

NAME            testSSL_cm
LOGFILE         /work1/tpalmer/testing/cm/cm1.log
SSL_LABEL       test_cm

SERVERSET testSSL_ss
{
  INFORMIXSERVER        ids1410fc3_ssl
  SLA ss_avail  DBSERVERS=ids1410fc3_ssl
}
